[0012] As a preferred solution of the present invention, the width of the first notch is smaller than that of the second notch.

[0013] As a preferred solution of the utility model, a wire cutting guide groove is formed on the right scissor blade, and a wire cutting guide rail column is inserted into the wire cutting guide groove. Under the guidance of the wire cutting guide rail column in the guide groove, the wire cutting guide groove of the right scissor blade opens and closes and cooperates with the left scissor blade to complete the wire cutting function.

[0014] A sock-turning machine comprises a scissor device and a sewing device. The scissor device is fixedly mounted on the sewing device and is used to cut the sewing thread on the sewing device.

DETAILED DESCRIPTION

[0030] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-Figure 7As shown, a scissors device for a sock sewing and turning machine comprises a scissors cylinder seat 1, wherein a piston 11 and a spring 12 are arranged inside the scissors cylinder seat 1, a scissors guide rail body 5 is fixedly installed on one side of the scissors cylinder seat 1, a guide rail groove 51 is formed inside the scissors guide rail body 5, a scissors push plate slider 2 and scissors 3 are arranged between the scissors cylinder seat 1 and the scissors guide rail body 5; the scissors guide rail body 5 comprises a first connector 6 and a second connector 4, wherein the scissors guide rail body 5 is connected to the upper end of the piston 11 through the first connector 6, and the scissors 3 are connected to the lower end of the scissors guide rail body 5 through the second connector 4; the upward movement of the piston 11 drives the scissors push plate slider 2 to move upward, and then drives the scissors 3 to move along the guide rail groove 51 to realize the thread cutting function.

[0032] The scissors 3 include a left scissor blade 31 and a right scissor blade 32, which are connected by a bolt assembly at the lower end, that is, a circular hole is formed at the lower end of the left scissor blade 31 and the right scissor blade 32, and the bolt passes through the circular holes of the left scissor blade 31 and the right scissor blade 32 and connects the left scissor blade 31 and the right scissor blade 32 through a nut. The left scissor blade 31 and the right scissor blade 32 are not fixedly connected, but are movably connected.

[0033] like Figure 1-2 As shown, the scissors 3 of the scissors device of the utility model are vertically arranged and the movement direction of the scissors 3 is also vertically up and down, which is not set in the same direction as the sewing setting to produce the sewing line. Accordingly, the scissors device can completely cut the sewing line without pulling the sewing line.

[0034] The guide rail groove 51 includes a first notch 511 , a second notch 512 and a connecting opening 513 connecting the first notch 511 and the second notch 512 . A raised thread trimming guide rail column 52 is formed in the middle of the connecting opening 513 . The width of the first notch 511 is smaller than that of the second notch 512 .

[0035] Specifically, the first notch 511 , the second notch 512 , and the connecting opening 513 form a guide rail groove 51 with a small opening at the lower end and a large opening at the upper end. The guide rail groove 51 cooperates with the trimmer guide rail column 52 to guide the up and down movement of the right scissor blade 32 of the trimmer guide rail column 52 .

[0036] A wire trimming guide groove 321 is formed on the right scissor blade 32. The shape of the wire trimming guide groove 321 is designed according to the position and shape of the guide groove 51 and the wire trimming guide column 52. The wire trimming guide groove 321 is inserted into the wire trimming guide column 52 of the guide groove 51. Under the guidance of the wire trimming guide column 52 in the guide groove 51, the wire trimming guide groove 321 of the right scissor blade 32 opens and closes and cooperates with the left scissor blade 31 to complete the wire trimming function.

[0037] Practical application of the scissors device: the piston 11 pushes the scissors push plate slider 2, and the scissors push plate slider 2 drives the left scissor blade 31 and the right scissor blade 32 to move upward along the guide groove 51 in the scissors guide body 5, the left scissor blade 31 and the right scissor blade 32 are vertically arranged, and the wire sheet 9 is horizontally arranged. The left scissor blade 31 and the right scissor blade 32 are perpendicular to the wire sheet 9 and approach the wire tip 91 of the wire sheet 9. Under the guiding action of the wire cutting guide groove 321 on the right scissor blade 32 and the wire cutting guide column 52 in the guide groove 51, the right scissor blade 32 performs an opening and closing action and cooperates with the left scissor blade 31 to complete the wire cutting.

[0038] like Figure 1-Figure 7 As shown, a sock sewing and turning machine includes a scissor device and a sewing device 200. The scissor device is fixedly installed on the sewing device 200, and the scissor device is used to cut the sewing thread on the sewing device 200.

[0039] An upper sewing needle 7 and a lower sewing needle 8 are arranged at the front end of the sewing device 200, and an angle is formed between the upper sewing needle 7 and the lower sewing needle 8. A guide wire piece 9 for sewing is arranged at the front end of the upper sewing needle 7, and the scissors device is located at the lower ends of the upper sewing needle 7, the lower sewing needle 8 and the guide wire piece 9.

[0040] The left scissor blade 31 and the right scissor blade 32 are arranged vertically, and the guide wire sheet 9 is arranged horizontally. The overlapping surface of the left scissor blade 31 and the right scissor blade 32 of the scissor device is perpendicular to the plane where the guide wire sheet 9 is located.

[0041] The wire piece 9 includes a wire tip 91, and the wire piece 9 is located at the upper end of the scissors 3. The distance between the wire tip 91 and the top of the scissors 3 is 0-19 mm.

[0042] The wire piece 9 is located at the lower end of the scissors 3, and the distance between the wire tip 91 and the top of the scissors 3 is 0-4mm.

[0043] Specifically, when the left scissor blade 31 and the right scissor blade 32 are in a waiting state below the conductor piece 9, the distance between the top of the scissors 3 and the wire tip 91 of the conductor piece 9 is 15-19 mm. After the left scissor blade 31 and the right scissor blade 32 move vertically upward to complete wire cutting, the height of the top of the scissors 3 is 2-4 mm higher than the wire tip 91 of the conductor piece 9.

[0044] When the left scissor blade 31 and the right scissor blade 32 of the utility model are in thread cutting operation, the thread cutting plane formed by the gradual contraction of the V-shaped opening is almost parallel to the plane of the guide wire sheet 9, and the overlapping surfaces of the left scissor blade 31 and the right scissor blade 32 are perpendicular to the plane where the guide wire sheet 9 is located. Accordingly, after the left scissor blade 31 and the right scissor blade 32 are closed after thread cutting, when the sewing device 200 moves backward to exit the sewing operation, the sewing thread that has not been completely cut can be pulled off, and at the same time, the sewing thread remaining on the guide wire sheet 9 can be protected from falling off, thereby ensuring the continuity of the next sewing operation.
